Figure 6-6 — Firmware Upgrade page
The Firmware Upgrade page is only for replacing the firmware that controls
all switcher operation. To insert your own HTML pages, see File
Management later in this chapter.
Insure that your PC is connected to the MPX 423 A switcher via the switcher’s
Ethernet port. Update the switcher firmware as follows:
1. Visit the Extron web site at www.extron.com.
2. Select the MPX 423 A product category from the “Product Shortcut” drop-
down box, and select the latest firmware file for download.
3. Note the folder to which you save the firmware file.
4. Connect the PC to the MPX 423 A switcher via the switcher’s Ethernet port.
5. Access the MPX 423 A switcher using the on-board Web server.
6. Click the Configuration tab.
7. Click the Firmware Upgrade link.
8. Click the Browse button. An open file window appears.
9. Navigate to the folder where you saved the firmware upgrade file. Select the
file.
Valid firmware files must have the file extension ‘.S19’. Any other file
extension is not a firmware upgrade.
The original factory-installed firmware is permanently available on the MPX
423 A switcher. If the attempted firmware upload fails for any reason, the
switcher automatically reverts to the factory-installed firmware.
12. Click the Open button.
13. Click the Upload button. The firmware upload to the MPX 423 A switcher may
take a few minutes.
File Management
The File Management page (located under the File Management tab), is a useful tool that allows
you to use and upload existing and custom Web pages. Custom pages can be developed using a
third-party Web page development program such as FrontPage or Dreamweaver. File
management also allows you to remove unnecessary or outdated files when they are no longer
needed.
